IT service catalog

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“As a service catalog is created, the CIO can start to see where the organization has redundancies, or if there are high-cost services with low demand that can be outsourced at a lower cost.” – Craig Symons

Today’s WhatIs.com Word of the Day is IT service catalog. An IT service catalog contains information about deliverables, prices, contact points and processes for requesting a service. Typically a catalog will have two views, a customer-facing view in which services are explained in plain English — and a technical view that documents exactly what is required to deliver each service in the catalog.

PICK chart

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“If the team decides that it is important that an idea be ranked as ‘extremely hard’ or ‘very high payoff’, you can make a note of that or place it along a quadrant accordingly, but try to encourage team members to think of the chart as only 4 choices. Ranking the ideas along a continuous scale is a waste of time since the relative ranking is not going to be recorded and analytical people tend to argue too much about where exactly along the scale an item belongs.” – Jon Wittwer

Today’s WhatIs.com Word of the Day is PICK chart, a visual tool for organizing ideas after brainstorming sessions. A PICK chart can to help an individual or group identify which ideas can be implemented easily and have a high payoff.

Outlook Anywhere

What do you call it when a tape drive repositions tape repeatedly? Shoeshining

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The process of stopping, rewinding and getting back up to speed is called repositioning or backhitching. Each reposition/backhitch can take as long as a few seconds. If you backhitch a lot, it’s called shoeshining because the tape activity mimics the movement of a cloth being used to shine shoes.”Curtis Preston

Today’s WhatIs.com Word of the Day is shoeshining, the repeated back and forth motion a tape drive makes when there is interruption in the data stream.

Write through vs write back

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Apple’s Xserve RAID allows you to choose which is more important to you–performance or integrity. If you choose write-back cache for performance reasons, the Xserve RAID will default to write-through cache if it detects that it is running on the UPS. Switching to write-through cache assures that nothing will remain in cache in the event of complete battery loss.” — W. Curtis Preston

Today’s WhatIs.com Word of the Day is write through, a storage method in which data is written into the cache and the corresponding main memory location at the same time.

After a failover, there has to be a failback

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“When preparing to return to your original office, test the systems and infrastructure to ensure they are working properly; ensure there is sufficient storage capacity to handle the returning systems and data; and ensure that sufficient network bandwidth is available for the failback.” – Paul Kirvan

Decision trees

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Unfortunately, many default settings on data mining and statistical software automatically create decision trees or rules sets that are preprogrammed to distribute the cases evenly. This can be a huge problem when dealing with infrequent events or otherwise unequal distributions. Another way of stating this is that the program assumes that the prior probabilities or “priors” are 50:50, or some other evenly distributed ratio.”Colleen McCue

Today’s WhatIs.com Word of the Day is decision tree, a graph that illustrates a decision-making process by listing every possible outcome as a branch of the tree.  (Usually the tree appears to be growing sideways.)

Decision trees are useful for providing team members with a common view of possible outcomes for discussion purposes — but they can also (gasp) be used to assign values to possible outcomes and actually frame what a decision’s consequences would look like.

MBABullshit has a good video illustrating how a decision tree might be used when deciding whether to sell lemonade or candy.

Stateless app is a misnomer

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Is the future of RIM all about Balance?

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Cloud orchestrator – automating the private cloud

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The orchestration software that drives the service catalog understands the processes required for each service listed in the catalog, as well what resources are available in the private cloud architecture to support it. When the user selects a service from the catalog, the orchestration system takes over, launching a series of automated tasks to allocate the server, storage and networking resources for the service.”Michael Brandenburg

Today’s WhatIs.com Word of the Day is cloud orchestrator, industry lingo for software that manages the interconnections and interactions among cloud-based and on-premises business units.
